Perhaps you should try some spelling variations:
"allocation optimisation algorithmssssssssssss" » "allocation optimization algorithmssssssssssss", "allocation optimization algorithmsssssssssssss", "allocation estimation algorithmssssssssssss", "allocation estimation algorithmsssssssssssss"
"parameter optimisation algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameter optimization algorithms", "parameter estimation algorithms"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"allocation optimisation algorithmssssssssssss\") OR (\"parameter optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( allocation optimisation algorithmssssssssssss ) OR ( parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("allocation optimisation algorithmssssssssssss") OR ("parameter optimisation algorithm"))*.
